Letters Patent No. 100,143,

IMPRovEMENT 1N sKY-LGHTs.

The Schedule referred to in these Letters Patent and making part of the same.

'l'o all whom yit may concern:

Be it knownI that I, GEORGE HAYES, of the city, v county, and State of New York, have invented a new and'nsefnl Improvement in the Construction of Skytiires, of Vwhich the following is a full, clear, and exact description, reference being had to the accompanying drawing forming partof this specification, and in which- Figure l represents a vertical section of the ouehalf or portion of a consent'atory-roof constructed according to my improvement;

Figure 2, a plan of the saine iii part;

Figure 3, a transverse section on a larger scale of a metallic bar, with its gutters and attachments used in the construction ot'saidroof; and

Figures 4, 5, 6, and 7, 4plan views of the details 0f the same.

Similar letters of reference indicate corresponding parts.

This improvement relates to sky-lights, conservatory, and other glazed metal roofs', and consists iii a novel construction of the same, whereby, while every provision is made for expansion and contraction, without straining the parts or breakage of the glass, lightness aud strength is securedto the structure, and the same may be put together cheaply and expeditiously, leakage is avoided, and putty to secure the glass dispensed with also provision made for carrying of water passing any of the joints, and, by using galvanized sheet metal, paint is rendered unnecessary.

Referringto the accompanying drawing, a prominent feature of this invention is a hollow metallic bar cording to the size of the roof, and which, ira-.connecsnpports of the roof, and, as applied to a conservatory root', runs from the ventilator B to the wooden curbing. Said hollow bars A are vcomposed of a sheet-metal body, a, bent to form reha-tes, b b, for support of the panes-or sheets ot' glass O along their one side or edge, and gutters c c for the escape of water beating or leaking into tliestrlicture.

Bracing the body a thus'construct-ed, and made to t'orni a part ot' the 'hollow metallic bar, is a lower V or other suitably-shaped sheet-metal molding d heut at its upper edges to overlap and clip the upper edges ot' thc gutters c c, as at e e, and holding in between it andthe body 'a at the base of the lattera Hat metal stay-plate j', the whole being secured together by rivets As thus constructed, the

said hollow bar has the appearance of a solid'lni'old'ed har. llie glasses C are secured iu the rebates b b by; means of sheet-metal caps D soldered on to the top ot the bar A, no putty being used in securing the. glass.

The ventilator B may he of any suitable construction, and is made to communicate by apertures g with gutters in the cross-beams that connect with the main gutters c c ot' the hars A, to carry ott the water formed. by condensation or leakage.

E E are the cross-beams or transoms, alsofornied hollow and ot' sheet metal, and providedon top with gutters i, connecting at their ends with the main gutiters c c.

The glasses C are arranged so that they forni or establish joints over the cross-gutters h.

They are restrained from sliding out ofplace by rest direction to the bars A, and extending s0 that they are covered at their ends by the cap-plates D. These clips cause any water which may not pass over theui to the foot otl the roof', but leaks through such joints,

toiind vits way into the cross-gutters beneath the clips.

By the'construction, as here shown, any water formed by condensation, or by leakage past any of the,A joints, is conducted by the main and cross-gutters to the foot of the roof or sky-light, and linally delivered by or through outlets t'.

What is here claimed, and desired to be secured by Letters Patent, is-

1. The metallic bar or rafter A formed of a hollow sheet-metal body (1., stay-*plateji and hollow molding d, titted together and arranged to forni rebates b b for the glasses, and gutters c c, substantially as specified. -"2. The combination of' the cap-plates D, with the hollow metal bars or rafters A, essentially as shown and described.

3. The clips I, in combination with the cross-gut- 'ters 7:-, and main gutters c c, substantially as specitied.

GEORGE HAYES.
